I see a post by blago in another thread mentioning having > 1 volume allowing for parallelization:
"...
@issaburst if you have plots at two drives (for ex. d:\plots\ and e:\plots), in miner's config you may set (parallely reading)
"Paths":["D:\plots","E:\plots"],
..."
and samples of config files where having individual drives addressed by the OS seems more popular. also the best for actual results? or just more common/easier for the avg user?
